Question

Kiran jogs at a speed of 6 miles per hour when there are no hills. He plans to jog up a mountain road, which will cause his
speed to decrease by r miles per hour. Which expression represents the time, t. in hour it will take him to job 8 miles up the
mountain road?

Answer 1

Answer:

The equation is $t = \frac{8}{6 - r}$

Step-by-step explanation:

First off, we know r is going to be subtracted from 6 somewhere in the expression since the problem says "decreasing by r miles per hour."

If we want to see how long it would take him to jog 8 miles up to the mountain road we would have to take 8 and divide it by 6 - r.

Therefore, the equation is $t = \frac{8}{6 - r}$
